Bioclimatic Analysis Based on the Climate of Greece: An Approach towards Minimization of Energy Consumption in Buildings

This research tries to design buildings depending on the local microclimate of the location, utilising solar energy and other environmental sources, as well as various natural climate phenomena.

As a result, energy consumption in the building sector is reduced while thermal comfort is provided to building users. The bioclimatic analysis of regions of Greece with various climatic features is carried out in this work. According to KENAK 2017, Greece's Prefectures are divided into four climate zones: A, B, C, and D. The bioclimatic study is carried out utilising the bioclimatic charts of the structures developed by the Olgyay brothers Victor and Aladar. The quantitative and qualitative bioclimatic charts of Victor & Aladar Olgyay are created for two Prefectures of each climate zone using the relevant climatic data from the National Meteorological Service. The average values of the passive demands for sun radiation, shade, wind, and humidity for each month and climate zone are computed using the quantitative bioclimatic charts. Passive heating and cooling strategies are defined by analysing qualitative bioclimatic charts. The regression lines and second degree polynomials equations are then produced using the charts of solar, radiant, wind, and humidity demands every month for each climate zone. These formulae can be used to easily compute passive thermal and cooling requirements for each month and for each climate zone the findings can be applied to areas with similar climates. As a result, this research can serve as a guide for building designers. They will be aware of the passive heating and cooling techniques they must employ based on the climatic zone of each building in order to ensure thermal comfort conditions for the occupants.
